The page had grown by accretion: model discovery scattered across five
cards with a search box each, one Save writing eight keys from the
bottom of a card that also held a second Save for something else, and a
banner apologising that a button "applies only the settings above it".
Now it reads in groups — Accounts, Models, Assistant & prompts, Site —
and every card is a <details> that folds, so Save & Close means
something. The rule is that each card saves exactly what it shows,
which is what removed the need for the banner.
Models is one workflow in three steps. Discover & test has a single
search box and a kind switch (chat / image / speech / transcription /
embedding); the five discovery calls are unchanged, the switch only
decides which one answers. Roster is what has been added, including the
image roster, which had no visible list before. Availability is the
chat model, the two allowed lists, the per-workflow image settings and
the slide reviewer, under one Save.
Splitting the eight-key save follows from that rule: Save & Close writes
the five retrieval and citation keys; Save availability writes the chat
model, both allowed lists, the reviewer and the three image-settings
PUTs. No route, request shape or setting key changed.
Switching kind clears the results first — a row button would otherwise
add an image model to the chat roster.
The kind switch dispatches its event through document.defaultView's
CustomEvent. jsdom refuses one built from another realm, and the
existing announceModelsChanged() has exactly that bug: its event is
built from the Node global, dispatchEvent refuses it, and a try/catch
swallows the error — so models-changed propagation has only ever been
source-grepped, never actually tested. Left alone here to keep this
change to one subject.

Adding a discovered model refreshed exactly one dropdown — the default-model
one, in the same card. Every other picker had been filled when the admin tab
loaded, behind a guard that makes its loader run once per visit, so the
Clinical Assistant chat model, the allowed-models list, the slide reviewer and
the image-model selects all kept the roster they were given. The model was
genuinely added; it simply could not be selected until the page was reloaded,
which reads as the add having failed.
Every mutation of the roster — add, remove, clear-all, enable/disable — now
dispatches `models-changed`, and the cards that list models listen and refetch.
The event carries no payload: a listener re-reads the list itself, so there is
one source of truth rather than a copy to keep in step. Same pattern as the
existing `assistant-image-roster` event.
Each listener clears its own guard before re-running, and returns early if a
load is already in flight. The assistant loader keeps unsaved drafts, so
re-running it costs nothing but a refreshed set of options.
The add toast said "now select it as default and click Set Default" — advice
that only made sense when the default dropdown was the one thing that updated.
Verified against a mutation: removing the guard reset fails the propagation
test, because the listener then fires into a loader that returns early.

**Fallbacks.** One image model meant a refusal, a rate limit or a model the
gateway had since dropped ended as a missing picture. Every workflow now tries
its model, then each fallback in order, stopping at the first that produces an
image. Primary plus two, capped: each hop is a paid request, and a chain long
enough to need a cap is long enough to surprise someone.
My Resources previously had no fallback at all — only the Clinical Assistant
did, and only one. That is backwards: a missing figure is most visible in a
deck, where it leaves a hole in a slide.
The retry rule is now a classifier that says *why*, rather than a boolean.
Transient faults, a 404 for a model the gateway does not have, and a content
refusal all move to the next model — a refusal because policy is a vendor
decision, not a fact about the request. 401/403 stop immediately (one gateway,
one set of credentials, the next model fails identically), as do 413 and any
other 4xx, which are malformed everywhere. Refusals are recognised from the
message: no provider sends a machine-readable reason and the status varies.
Each hop re-leases the job, so a chain cannot outlive its claim and let a second
worker repeat the same paid work, and the row records the model actually being
paid for so a picture made by the third model is not attributed to the first.
The old singular `fallback_image_model` is still read, so an existing
configuration keeps working without anyone re-entering it.
**Library.** Documents/Images tabs in My Resources, with a real grid: fixed
aspect tiles so the rows line up whatever shape the pictures are, a source badge
on the picture, two-line prompt, hover lift, shimmer skeletons while thumbnails
land, and a lightbox that closes on Escape or the backdrop and restores focus.
Actions are hidden on hover only behind `@media (hover:hover)` — hiding delete
behind :hover would put it out of reach on touch and keyboard.
Downloads go through privateImageBlob rather than a bare `<a download href>`: a
mobile client's session is a bearer token an anchor cannot send, and these
assets are served no-store on purpose.
The gallery lives in My Resources only. Assistant images appear in it, which was
the point; the assistant page does not grow a gallery of its own, and a test
asserts no assistant module lists the endpoint.
